Someone who constantly refers to their friends as "my buddy (insert name here)", even though you may have met that person 100 times.

This person generally has so many cousins and aquaintances that he can't keep track of who knows who - he is only confident that he knows everyone. Or at least knows someone who knows someone who knows everyone.

My buddy was a large doll that was marketed for boys. It had a large head and plush body and was supose to be "a boy's best friend." Parents who were against violence usually bought this doll as a replacement for G.I. Joe.
My brother got one for christmas one year, that doll is just creepy. Like a dolled up version of chucky.
